'5 Claims.

My invention relates to improvements in dispensing devices for collapsible tubes and the like wherein a pair of pinions mounted in engaging relation with a pair oi depressed racks upon either side of a longitudinally disposed raisedbed portion are connected rigidly by a roller of smaller diameter than the diameter of the pinions, said roller and pinions of diflerent diameters thus operating in conjunctionwith said 0 raised bed portion to completely extrudethe contents 01' a collapsible tube on said b'ed portion by a rolling, and also a rubbing, movement toward the dispensing end of said tube when said rollers are rolled upon said racks and toward the said dispensing end, whereby the contents of said tube may be efliciently and completely extruded.

The primary object of the present invention is to provide a new and improved dispensing device for collapsible tubes and the like.

Another object of the present invention is to provide a new and improved device of the character set forth which is extremely simple and economical in construction and operation and which will provide an improved means for completely extruding thecontents of a collap-,- sible tube. a

A further object is to provide an improved dispensing device for collapsible tubes and the like, which'will impart a rolling, and also a rubbing, motion or movement toward the dispensing end of said tube while'collapsing the tube whereby the same may be eiliciently collapsed and the contents thereof completely removed.

A still further object of the present invention is to provide a new and improved device as described which may be easily constructed of sheet metal to provide a maximum economy of construction and the fewest possible number 'of parts.

The invention consists in the particular arrangement and construction of the parts disclosed in the drawing forming a part of the present application, wherein like characters of reference are used to designate similar parts thruout the said specification and drawing and in which Fig. 1 is a vertical, longitudinal, sectional view of my improved device, disclosing a collapsible tube partially extruded of its contents;

Fig. 2 is a broken plan view thereof with the cover removed;

Fig. 3 is a transverse sectional view taken on line 3--3 of Fig. 1 in the direction indicated; and

Fig. 4 is a similar transverse sectional view disclosing a modified form of the improvement.

Referring to the drawing, the numeral 1 is used to designate in general a body formed preferably of sheet-metal, or the like, and having a centrally disposed longitudinal raised bed portion 2 with depressed portions 3 lying upon each side thereof and perforated to provide a pair of racks 4. Mounted in engaging relation with said racks, is a pair of pinions 6 rigidly connected by a roller 7 of smaller diameter than the pitch diameter of the pinions 6, the purpose of which will hereinafter be more fully set forth, said roller 7 lying in close proximity and extending transversely across said bed portion 2 of the body 1 The pinions 6 are each provided with an extending trunnion 8 which are engaged by longitudinally disposed ,ribs 9 formed integral with the body 1 and extending longitudinally thereof and over the said trunnions 8 in order to retain the pinions 6 inengaging relation with their respective racks 4, as disclosed in Fig. 3 of the drawing. One end of the body 1 is provided with an extended portion 11 apertured centrally as at 12 to receive and retain the neck or dispensing end 14 of a collapsible tube 16 upon the bed portion 2 of the device.

In Fig. 4 of the drawing I have disclosed a modification wherein the trunnions 8' are extended exteriorly of the body 1, thru longitudinally disposed slots 9', which take the place of the ribs 9, to retain said pinions 6 in engaging relation with their respective racks 4. The trun-, nions 8' are provided with suitably knurled knobs 17 whereby the device may be operated from the outside of the device.

A suitable cover 18 may be provided. p

In operation, the collapsible tube 16, or the. like, is placed upon the bed portion 2 and the dispensing end 14 of said tube 16 inserted thru the aperture 12 of the extension 11 and the roller 7 is then rolled upon the opposite flattened end of said tube 16.

When it is desired to extrude a portion of the contents of the tube 16, the pinions 6 are rolled upon their respective racks 4 and, by reason of the smaller diameter of the roller '7, the tube 16 will be collapsed upon the bed portion 2 bythe roller '7 lying in close proximity thereto with a rolling, and also a rubbing, motion toward-the dispensing end of said tube 16 whereby the contents of, said tube may be completely extruded as the roller 7 passes over it.

I am aware that the present state of the art and the like, I therefore, do not wish to include such a device bro 2' f f' v discloses dispensing devices for collapsible tubes,

but- Having thus desc bed my invention, what I claim and desire to secure by LettersPatent isl. A dispensing device for collapsible tubes I comprising a body provided with a centrally disposed longitudinal bed portion and a depressed rack on eachside of. said bed portion; a pair of pinions mounted in engaging relation with said racks; and a roller of a lesser diameter than the pitch diameter of the pinions rigidly connected to said pinions and lying in close proximity to said bed portion whereby the contents of a collapsible tube upon said bed portion may be extruded from said tube by a rolling, and also a rubbing, movement towards the dispensing end of said tube by said roller when said pinions are moved along their racks, toward said dispensing end whereby said contents may be substantially entirely removed from said tube. I Y

2. A- dispensing device for collapsible tubes comprising a body provided with a centrally disrubbing, movement towards the dispensing end of said tube by said roller-when said pinions are moved along their racks toward said dispensing end whereby said contents may'be substantially entirely removed from said tube; and longitudinally disposed ribs formed integral with said body'for retaining said pinions in engaging relation with said racks.

3. A dispensing device for collapsible tubes comprising a body having a centrally disposed longitudinal body portion and a depressed portionon each side thereof perforated to form racks; a pair of pinions mounted in engaging relation with said racks and each having a trunnion projecting therefrom; and a roller of smaller diameter than the pitch diameter of said pinions rigidly connecting said pinions and lying in close proximity to said bed portion,

whereby the contents of a-collapsible tube upon said bed portion may be extruded therefromby a rolling and also a rubbing movement toward the dispensing end of said tube by said roller when said pinions are moved along. their racks toward said dispensing end, whereby said contents may be substantially entirely extruded proximity to said bed portion, whereby the con-' tents of a collapsible tube upon said bed portion may be extruded therefrom by a rolling and also arubbing movement toward the dispensing end of said .tube by said roller when said pinions are moved along their racks toward said dispensing end, whereby said contents may be substantially entirely extruded from said tube; and longitudinally disposed ribs formed: integral with said body and engaging the trunnions upon said pinions for retainingsaid pinions in engaging relation with said racks.

5. A dispensing device for collapsible tubes comprising a sheet metal body having a centrally disposed longitudinal bed portion formed therein and depressed portions on each side thereof perforated to form racks, and likewise having longitudinally disposed ribs formed in- 1 tegral with said sheet metal body; a pair of pinions mounted in engaging relation with said racksand each having a trunnion engaging the ribs to retain said pinions inengaging relation; and a roller. having a smaller diameter than the diameter of said pinions rigidly connecting said pinions and lying in close proximity to said bed portion, whereby the contentsof a collapmble tube upon said bed portion may-be extruded therefrom by a rolling, and also a rubbing, 3 movement towards the dispensing end of said tube, when said rollers are rolled toward said dispensing end, whereby said contents may be completely extruded from said tube.
